Solve the system of equations.
3x + 2y = 56
5x-2y =24

Step-by-step explanation:

PRIMERO encuentras x

3x + 2y = 56

5x - 2y = 24

8x        = 80

x = 80/ 8 = 10

LUEGO PARA ENCONTRAR y TOMAS cualquiera de las dos DE LAS

ECUACIONES Y SUSTITUYES x

3(10) + 2y = 56

30 + 2y = 56

y = 56 - 30/2 = 13

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

answer is c

step-by-step explanation:

81/12=324/x

x=48
